What are the advantages and disadvantages of chemistry in the environment

Answer 1

What Are the Advantages of Chemical Energy?

1. Most forms of chemical energy are released through combustion.

Combustion is one of the easiest methods to obtain energy. Instant power is received through the consumption of the energy resource. The efficiencies of that combustion can be controlled and directly maintained so the most possible energy can be harvested, making it a cheap and effective way to receive the energy forms that are needed.

2. It is an easy form of energy to stockpile.

If you’ve got a fireplace or a woodstove, then there’s a good chance you have a pile of wood in your backyard somewhere. That is just one example of how easy it is to stockpile a chemical energy resource. Even the starting of a campfire or lighting the charcoal for a grill shows how easy it is to take advantage of what chemical energy can provide.

3. Many forms of chemical energy have high density loads.

The power that chemical energy can release through the breakage of bonds is immense. That high-density load is enough for us to fuel transportation networks, fly people into space, and perhaps go beyond the solar system one day. Compared to other energy resources, chemical energy has one of the highest densities that is available to us, which means we can have a substantial amount of power to use with minimal available resources.

4. It is reasonably efficient.

Chemical energy requires the presence of oxygen to be effective. When the environment can be controlled so that the oxygen can begin the combustion process, the efficiency of this energy resource can be quite high. As long as the bonds can be ignited so their energy can be released, a properly controlled environment can direct that energy into specific outcomes.

5. The environmental effects can be controlled.

Although combustion naturally releases emissions into the atmosphere that could be potentially harmful, there are capture and storage technologies which can be utilized to limit the damage. One example of this technology would be clean coal. By capturing the carbon and other harmful gas and particulate emissions for storage, we gain the benefit of the chemical energy while reducing the risks of a negative outcome occurring

What Are the Disadvantages of Chemical Energy?

1. It isn’t a sustainable form of energy.

Chemical energy resources can be replaced, but they cannot be replenished. Think of it like this. It’s cold outside, so you grab a couple of logs to put them into your fireplace. Then you light them to create a fire. That fire receives energy, in part, due to the chemical energy found in the wood. Over time, that energy is consumed and the wood turns to ash. Can you turn that ash into more wood? No. Can you get more wood? Yes.

2. It can be expensive.

Because most forms of chemical energy come from organic or naturally occurring items, accessing the resource can be quite expensive. We must mine coal before we can burn it. One must cut wood to size so it can fit into the fireplace or woodstove and that occurs after the tree has been harvested. And, since many of these products release particulates into the atmosphere, there are costly regulations in place to prevent excessive emissions.

3. Some forms of chemical energy are quite rare.

Let’s look at nuclear energy for this example of a disadvantage. Most nuclear facilities rely on uranium as a fuel. Uranium is such a scarce resource that some nations have not located any deposits of it within their borders. Once that uranium is depleted, more must be obtained. That rarity not only increases costs and deals with sustainability issues, but it also means that technologies used to access the chemical energy can become useless over time.

4. It can produce harmful waste.

Many forms of chemical energy release radiation as part of the combustive process. That radiation isn’t necessarily dangerous when it is well-controlled, but it can be deadly under the right circumstances. Issues at Chernobyl and Fukushima have showed us just how powerful chemical energy reactions can be when something goes wrong. Many radioactive isotopes have a long half-life, sometimes thousands of years, which means a catastrophic situation can be devastating to a local environment.

5. It can be used to create devastating weapons.

The rhetoric between the United States and North Korea, which escalated in 2017 to unprecedented levels since the armed truce was signed between the nations to stop the Korean War, shows us how chemical energy can be used for destructive purposes. Nuclear weapons use this form of energy. The devastation in Japan from the US dropping two of these weapons cost hundreds of thousands of lives over time. There are enough nuclear weapons today to completely devastate the world if they were all fired.

Explanation:

advantages of chemicals in our daily life :

⇒ one of the most important advantage in the field of chemistry was the invention of "plastics". plastics have replaced many other materials as they handy and economical.

⇒ another two important chemicals are acids and bases. acids are present in orange and lemon which are tangy and sharp and are also present in fizzy drinks and vinegar which is used for digestion.

⇒ the baking soda is acts as a medicine to put on bee stings which are acidic in nature

disadvantages of chemicals :

⇒ the use of plastics has an adverse effect on the environment. though plastics are useful, it is non biodegradable and is harmful

⇒ the excessive use of fertilizers can spoil the environment and improper usage can result in failure of crops in agriculture and is harmful for the micro organisms in the soil.
